1.GREENPLUM的安装和部署

GREENPLUM的安装和部署

在虚拟机上安装greenplum:
1.操作系统redhat 2.6.18-53.el5xen
2.安装介质 greenplum-db-4.2.2.0-build-3-RHEL5-i386.zip
3.准备单机上单机版安装,安装一个master节点,并安装两个segment
4.虚拟机磁盘空间情况:

[root@mdw ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 8.6G 2.2G 5.9G 27% /
/dev/sda5 14G 164M 13G 2% /data
/dev/sda1 99M 18M 77M 19% /boot
5.因为greenplum4.1只支持UTF-8字符集,所以在建立安装用户的时候需要把用户的默认字符集设置为utf-8,greenplum4.2能否支持其他字符集还待证实。
(注:greenplum-db-4.1的安装方法也是一样的)

1.1 LINUX系统关闭防火墙
因为greenplum集群各个节点是通过 ssh协议来互相访问的,所以需要关闭防火墙。

.3.1.1可以在安装linux的过程中关闭掉,
要关闭防护墙,安装LINUX的时候可以在firewall选项选择:disabled

这个玩意也关掉:

.3.1.2对已经安装好的linux使用以下方法来关闭
关闭SELinux的方法:
1、修改/etc/selinux/config文件中的SELINUX="" 为 disabled ,然后重启。
2、使用命令setenforce 0 ,不需要重启。
注:
setenforce 1 是设置SELinux 成为enforcing模式
setenforce 0 是设置SELinux 成为permissive模式
1.2 编辑/etc/sysctl.conf 和/etc/security/limits.conf
.3.2.1编辑sysctl.conf修改或添加系统参数
使用root用户编辑:

vi /etc/sysctl.conf
kernel.sem = 250 64000 100 512
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
net.ipv4.tcp_syncookies = 1
net.ipv4.ip_forward = 0
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_max_syn_backlog=4096
net.ipv4.conf.all.arp_filter = 1
net.ipv4.conf.default.arp_filter = 1
net.core.netdev_max_backlog=10000
vm.overcommit_memory=2

.3.2.2编辑sysctl.conf修改或添加系统参数
使用root用户编辑:

vi /etc/security/limits.conf

  • soft nofile 65536
  • hard nofile 65536
  • soft nproc 131072
  • hard nproc 131072

1.3 修改主节点/etc/hosts
使用root用户编辑/etc/hosts文件:
[root@mdw security]# cat /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 mdw localhost.localdomain localhost
#--hcb----::1 localhost6.localdomain6 localhost6

192.168.153.190 mdw mdw
192.168.153.190 sdw1 sdw1
192.168.153.190 sdw2 sdw2

1.4 创建gpadmin用户(greenplum默认的超级用户)
使用root用户:
建立用户组gpadmin
groupadd gpadmin
建立用户gpadmin
useradd -m -g gpadmin gpadmin
passwd gpadmin

将/data目录的属主修改为gpadmin
chown –R gpadmin:gpadmin /data

/data目录将是我们安装greemplum的目录
gpadmin用户将是我们安装greemplum的用户

使用gpadmin用户:
在/data下创建master、dbseg1和dbseg2目录
su -l gpadmin
cd /data
mkdir master
mkdir dbseg1
mkdir dbseg2

1.5 解压安装文件输入安装路径并赋权给gpadmin
将安装介质greenplum-db-4.2.2.0-build-3-RHEL5-i386.zip上传到/home/gpadmin目录下。
解压greenplum-db-4.2.2.0-build-3-RHEL5-i386.zip
得到greenplum-db-4.2.2.0-build-3-RHEL5-i386.bin

用gpadmin用户执行这个bin文件:
./ greenplum-db-4.2.2.0-build-3-RHEL5-i386.bin
显示一堆文字,按回车键直到显示:


Do you accept the Greenplum Database license agreement? [yes|no]


输入: yes ,回车


Provide the installation path for Greenplum Database or press ENTER to
accept the default installation path: /usr/local/greenplum-db- 4.2.2.0


输入: /data/greenplum-db-4.2.2.0
<<--如果这个目录不存在的话安装程序会询问是否要创建


Install Greenplum Database into ? [yes|no]


输入: yes ,回车


/data/greenplum-db-4.2.2.0 does not exist. <<--是否要创建greenplum-db-4.2.2.0这个目录?
Create /data/greenplum-db-4.2.2.0 ? [yes|no]
(Selecting no will exit the installer)


Yes


[Optional] Provide the path to a previous installation of Greenplum Database,
or press ENTER to skip this step. e.g. /usr/local/greenplum-db-4.1.1.3

This installation step will migrate any Greenplum Database extensions from the
provided path to the version currently being installed. This step is optional
and can be run later with:
gppkg --migrate /data/greenplum-db-4.2.2.0


按回车

Extracting product to /data/greenplum-db-4.2.2.0

Skipping migration of Greenplum Database extensions...


Installation complete.
Greenplum Database is installed in /data/greenplum-db-4.2.2.0

Greenplum Database documentation is available for download
at http://powerlink.emc.com.
*> ******************************************************************************

OK,这一步完成。
1.6 创建all_host和seg_host文件
进入目录/home/gpadmin
mkdir gpconfigs
cd gpconfigs

vi all_hosts <<--包含master和segment的全部主机名称
mdw
sdw1
sdw2

vi all_segs <<--只包含segment的主机名称
sdw1
sdw2
1.7 设置安装用户的环境变量
编辑gpadmin用户的启动文件,在末尾加入greenplum工具路径
vi .bash_profile
source /data/greenplum-db-4.2.2.0/greenplum_path.sh

执行一下:
source /home/gpadmin/.bash_profile

[gpadmin@mdw gpconfigs]$
编辑/home/gpadmin/.bashrc
添加 export MASTER_DATA_DIRECTORY=/data/master/gpseg-1,
然后执行source /home/gpadmin/.bashrc。

1.8 为安装用户设置各个节点的SSH连接
用greenplum的gpssh-exkeys工具为所有master和segment创建gpadmin用户无需输入密码的信任连接。
[gpadmin@mdw ~]$ gpssh-exkeys -f /home/gpadmin/gpconfigs/all_hosts
[STEP 1 of 5] create local ID and authorize on local host
[STEP 2 of 5] keyscan all hosts and update known_hosts file
[STEP 3 of 5] authorize current user on remote hosts
... send to sdw1
... send to sdw2
[STEP 4 of 5] determine common authentication file content
[STEP 5 of 5] copy authentication files to all remote hosts
... finished key exchange with sdw1
... finished key exchange with sdw2
[INFO] completed successfully

测试各个节点是否能连通
gpssh -f ./all_hosts <<--单机版的可以不测这个东西

[gpadmin@mdw gpconfigs]$ gpssh -h mdw
=> echo $HOSTNAME
[mdw] mdw
=> exit
[gpadmin@mdw gpconfigs]$ gpssh -h sdw1
=> echo $HOSTNAME
[sdw1] mdw
=> exit
[gpadmin@mdw gpconfigs]$ gpssh -h sdw2
=> echo $HOSTNAME
[sdw2] mdw
=> exit
1.9 编辑安装配置文件gpinitsystem_config
将/data/greenplum-db-4.2.2.0/docs/cli_help/gpconfigs/gpinitsystem_config
复制到/home/gpadmin/gpconfigs
然后编辑之:

vi gpinitsystem_config

1.10 初始化数据库(即安装)

用root用户修改192.168.153.190上 /etc/ssh/ssh_config
编辑 GSSAPIAuthentication 为no

用gpadin用户执行初始化greenplum系统的配置文件
